ELECTRIC SIGNALING SYSTEIVI FOR THE TELECONTROL 0F GUNS OR THE LIKE.

Application flied May 13, 1922. Serial No. 560560.

To a whom it may concern:

Be it known that I, BRUNO Gri icn. a citizen of the German Empire, residing at Derlin. Germany. have invented certain new and useful Improvements in an Electric Signaling System for the 'Ielecontrol of Guns or the like, of which the following is a specilication.

Owing to the long time of flight of the projectile of far-reaching guns of latef't type. the so-called distance of the target determined by the range finders must be corrected in the hailistic range wantethhj the artillerist. For this purpose. certain corrections: for instance, for the air weight. existing when tiring, i'or ahnm'mal pmvder temperature. for wind or for the decrease and increase of the range during the time of flight. are calculated or taken from schedules and applied to the distance. of the target. As known, said corrections depend upon the time of flight of the projectile.

The present. invention has for its object to provide simple adjusting means for mechanicall v-and automatically representing the corrections aimed at.

As the scale, that. transmits to the guns the angle of inclination. e. g. angular values. is gauged for distance, e. g. longitudinal values. the distance of the gauge marks from each other mustcorrcspond to the mean horizontal velocity of the projectile. which is equal to the quotient of the linear distance of the. target divided by the time of flight.

As the distance scale, which is to transmit to the guns or the like the angle of inclination. contains thus the time of flight, this can he attained by mechanically coupling to the transmission gear, intermediate said scale and the transmitters of av fire control apparatus at a central station for transmitting tbe adjustment of said scale to said transmitters. a multiplication gear. which automati ally multiplies the time of flight. existing in said scale by any other ballistic correction. for instance the increase and decrease of the'range per time unit. adjusted on a separate scale and adds said multiplication product, through a planet-wheel, for instance, to the transmission gear leading to the transmitters.

This arrangement has the further essential advantage that the ballistic range wanted by the artillerist can at any time be readolf and that the value of the correction varies continuously. which was not possible with the hitherto known arrangements.

The accompanying drawing shows :1 diagrannnatic elevation of theimproved arrangement, in a preferred form of construction.

By the adjustment of the distance of the tar 'eton a revolahle scale I mounted in a c. g (not shown) of the apparatus, at the same time a bevel wheel 2, a'planct-wheel 3. and a shaft 4, are turned. The latter moves. through a pinion 5 and a worm (i, the transmitters 2G and 27. The latter are atso mounted in the casing of the apparatus and connected in a way known in the art to electric receivers on the guns. The movement of the revoluhle scale 1 is further transmitted through a second hevel wheel 7 on its axle, a bevel wheel 8, and a bevel gearing 10, 11, to a screw-spindle 12. The latter is supported in a yoke 13 and carries a sliding block it which is threaded thereon. 'henthe distance scale 1 is adjusted to the value 0. said sliding block lies in line with the axis of shaft 9. The yoke- 13 carrying the spindle it? can he swung around through a bevel gearing 15. 1G operated from a hand wheel 17. The latter turns a pointer 15 on a scale 19 gauged for the increase and decrease of the range per time unit. The sliding block 14 is thus swung around. by turning said hand wheel 17. corresponding to the increase or decrease of the range per time unit. By the revolution of the distance scale 1. which contains the time of flight. the sliding block ll is radialh displaced corresponding to the time. of flight. of the projectile.

The sliding block 14 is in engagementwith a T-shaped slotted race 20, located parallel to the zero angular position of the yoke. 13. This slotted race carries a rack 21 extending at right angles to the race and being slidingly disposed in guide blocks 21 so that the race can move at right angles to its own slot. Said rack is in gear with a pinion 2:2. which. through its shaft 23 and bevel gearings 28. 29, turns the double bevel wheel 24, 25 loosely mounted on the shafts .ruuu

The bevel wheel is in gear with the planet-wheel 3, to which it transmits its movement as an addition, which is thus communicated to the transmitters 26 and 27 through bevel wheel 5 and \vorm G.

The idea of the invention is not limited to one single scale 19 gauged for the increase and decrease of the range per minnte, as also the remaining corrections can be separately or commonly transmitted to the bevel wheel 16 in a way known in the art, for instance through planet-gearings.

What I claim, is:

1. In an electricsignaling system for the telecontrol of guns, in combination an electric transmitter ata central station adapt-- ed to actuate an electric receiver on the guns connected to said transmitter, a range scale containing the time of flight factor, an epie yclie (planet) gear interposed between said transmitter and said range scale, a separate scale for the rate of change of range, and a multiplication system comprising one member mechanically moved by said range scale, av second member n'ieehanically moved by said separate rate of change of range scale, and a third member of said system, moved corresponding to the product of the adjustment given said scales and operating upon said epieyclie gear, so that the movement of said third member is added to the first range adjustment of said transmitter.

2. In an electric signaling system for the teleeontrol of guns in combination a plurality of transmitters for coarse and fine adjustment adapted to actuate a plurality of coarse and line receivers on the guns connected to said transmitters. a range scale containing the time of flight factor, an epicyclic gear interposed between said transmitters and said range scale, a separate scale for the rate of change of range and a multiplieation gear, comprising a yoke mechanically moved by the adjustment of said separate scale, a screw-threaded spindle rotatably mounted in said yoke and adapted to be rotated by the adjustmentor' said range scale, a sliding block threaded on said spindle and adjustable by said spindle rotation, and a sliding rack bar having a slot engaging said bloclt, said bar adapted to be moved corresponding to the product of the amounts of movements of said yoke and of said block and operating upon said epicyclie gear str that. the movement gf. said raelt bar is added to the first range adjustment of said transmitters.

In testimony whereof I attiti my signa ture.

BRUNO GLUER.
